_ENDing a program...

Hello:
I have been researching how to end a program, giving the user an opportunity to end the program, or myself in the coding process via a FOR loop to do so. I have found examples involving "end" and "_end" or "cend" (?) but am unsure how to implement it correctly, what it will do exactly, and when it will do it. I need to integrate this into my code. Please explain with a commented ( //--) example if possible...

Thank-you in advance,
Mansoor

I think you are looking for exit(). It terminates your program when called.

Code:

---

int main()
{
    for(int i = 0; i < 100; ++i)
    {
        if(i == 50) exit(0);  // Terminates your program when i reaches 50
    }

    return 0;
}

Thank-you for your reply. :wave::p:wave::thumb:

A little modified version can be like

Code:

---

  char szText[128] = {0};

  for (int i = 1; i < 10000; i++) // A long loop
  {
    sprintf(szText , "%d) Hello World\n" , i++);
    printf(szText);

    if (kbhit())
    {
      char key = _getch();

      if ('q' == key)
        break;
    }

  }

---

Here, the loop will be terminated, if it gets complete or user press "q" key.
